The process has been delayed due to the lack of specialised tools and equipment needed for the partial demolition of the building, which must be precise.

"There has been delay in carrying out the demolition processes, as there is a real need to extra careful, because some parts of the headquarters building are not affected" by the demolition order, Tanesco executive director for investment, Khalid James said.

"We are destroying only some of the property, and are required to protect other properties which are not covered by the demolition order," he explained on Monday.

The directive to complete the demolition by February 1 was given by the permanent secretary at the ministry of works, transport and communications, Mr Joseph Nyamhanga.

"I want the demolition processes to be completed by 1st February, so that construction of the Ubungo Interchange project kicks off as soon as possible," he said, adding that construction of the interchange is scheduled to start before the end of February.

"Constructors are now relocating some social facilities including water and gas pipelines, as well as electricity and communication cables," he said, noting that the relocation is slated to be completed this February.
